SUPPORT FOR SPINNING-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 412,631, dated October 1, 1889.

Serial No. 277,429. (No model.)

To all 1071 0722 it may concern:

Be it known that I, THOMAS H. LOGAN, of Lowell, in the county of Middlesex and State of )lassachusctts, have invented certain new and useful Improvements inSupports for Spinning-Spindles, of which the followin g is a specitication.

My invention has relation to spindles for spinning-machines, and has for its object such improvements in the supports for spindles as will overcome much of the friction heretofore encountered in running them, and thereby, as a consequence, greatly reducing the power and expense of driving the same.

To the foregoing ends myinvention consists of a construction, as hereinafter described and claimed, whereby the spindle is vertically supported entirely by the step, while the lateral support for the same consists entirely of an anti-friction ball-bearing.

For a full and clear understanding of my invention, reference is to be had to the accom panyin g drawings, and the letters of reference marked thereon, forming a part of this speci- 2 5 iication, of which drawings- Figure 1 is avertical section of the spindlesupport and its adjuncts, illustrating my improvements, the spindle being shown in elevation and in position in its support. Fig. 2 is a sectional detail view showing a modified form of one feature of the invention. Fig. 3 is a detail view similar to Fig. 1, but showing the anti-friction balls arranged on aline with the band-pull.

In the drawings, a designates the spindle; b, the sleeve-whirl; c, the bolster-case, and d the spindle-rail, all of usual form and function, excepting as hereinafter mentioned. The bolster-case c is secured to the rail d by means of a nut c, with which is combined an oil reservoir or cup f, provided with a stepeseat g, in which the fiat step 71 is secured in anysuitable manner.

'5 designates a hole formed in the side of th oil-reservoir f, by means of which the lubricant may be supplied to the foot and step of the spindle.

The not e is constructed so as to be screwed upon thelowerend of theboistcr-case c,-thereby securing the latter device to therail d and supporting its combined oil-reservoirand stepseat in proper position, all as clearly represented in Fig. 1, affording means for the purpose specified, which are very simple and economic of construction.

As shown in Fig. 1, the sleeve-whirl extends down over the upper end of the bolster-case, the latter being provided with a rounded offsetj ata point just below or as near as desired on the line of the baud-pull on the whirl, a ring it being forced into the lower end of the sleeve-whirl, so as to leave a space between the upper face of the ring 70, the offset j of the bolstercase c, and the inner surface of the whirl b, in which space is arranged a circle of anti-friction balls Z. As the bore of the bolster-case is appreciably larger than the diameter of the spindle, as is the bore of the sleeve-whirl larger than the diameter of the upper on d of the bolster-case, substantially the entire lateral support for the spindle is afforded by the circle of anti-friction balls Z, the spindle being supported vertically wholly by the step 71. With this construction no lubrication of the lateral bearing of the spindle 7 5 is required and the friction of the same is reduced to a minimurmthere being no appreciable increase of friction by increasing the ten sion or pull on the spindle-drivingband. Substantially the only friction between the spin- 8o dle and its bearings in the operation of the former will be between the foot of the spindle and the step h, and this will be inconsiderable.

It is obvious that many changes may be made in the form and arrangement of parts constituting my invention without departing from the nature or spirit thereof. For example, the parts shown in Fig. 1 may be so constructed as to bring the circle of anti-friction balls 1 on a line with the band-pull, as shown in Fig. 3; or the circle of anti-friction balls I may be arranged between the outer surface of the lower portion of the sleeve-whirl and the bolster-case c, in which case the upper portion of the bolster-case will be constructed 5 so as to surround the lower portion of the SleQ-Ve'Whll'l, as shown in Fig, 23. In all instances, however, the lateral bearing or support for the spindle will consist of a circle of anti-friction balls interposed between the spindle or whirl secured to the spindle and the bolster-case or its equivalent. It will be understood, of course, that the anti-friction balls I and the parts in contact therewith will be formed of metal hardened to the utmost degree, so as to avoid Wear.

What I claim is 1. A spindle and flat step for supporting the same vertically, combined with a bolstercase, awhirl secured to the spindle, and a cirole of anti-friction balls constructed and arranged solely to form a lateral bearing or support for the spindle interposed between the whirl and bolster-case, as set forth.
